If you are like me, then you are always carrying around extra stuff for the family or kids sports or just stuff in general. I cleaned out all the crap and surprisingly, just gi's for judo class, and soccer stuff and football gear, lifted some weight off the car!!!! Im hoping to see a small change in the tank, even though i doubt its alot, anything helps :)

Here's a novel idea...go on a diet...the average American adult being 37 lbs overweight, the "lard effect" on MPG comes into play every time the engine is started.

extra weight not only makes your mph worse, it also puts an extra strain on your engine, puts more wear and tear on the roads and increases your braking distance. On the positive side, you might get away without renting storage space if you can pack enough stuff in your car.

I've heard it does save gas the less weight you have in your car.

it might save gas but i rather have more gas in the tank than i need, than to need it and not have it just for saving a few cents on the next fill up...

I leave my 100lb full size spare tire on my garage floor. That's 100 fewer pounds that needs fuel to accelerate everywhere I go. I need to lose about 10 lbs next. Doh!

ummm..with the helium idea: ya might wanna tie off to another vehicle that runs normal down the road so you don't wind up in Canada or something. Just cut the ties at your destination. You'll need balloons on your tires or something and better shocks for the landing though...

Unless your vehicle is full with passengers all the time it does not matter.

Don't carry a lot of weight. Remember gas weighs 7 pounds per gallon. So, you should always be driving on empty which is not practical.

Try helium in the car..........with enough, you might be able to float to your destination and save some gas? ;)

Yes, but I bought a quad cab partly for the reason of being able to keep all my stuff inside the cab instead of in a toolbox in the back of the truck. Its pretty rare that my back seats get folded down.

Though, if you live in a state with winter, the extra weight can help with traction.

.....F = M * A,.,,,and theres inertia ,more mass takes longer to stop ,so you can coast(saves fuel) farther with all that mass once you get it going :) kinda equals out

I had about 500lbs of stuff in my old Civic when I drove from CT to TX, still got 38mpg since I stuck to about 68mph. Of course, had it been city driving, mpg would have dropped a lot more.

I can tell the difference in performance between my 130lb gf in the passenger seat and my 200lb friend. With 2 or 3 people in my car, I have to press the accelerator significantly harder to get up to speed.

It takes about 2hp to move 200lbs from 0-30mph at the rate of normal city traffic acceleration.

Hi Folks,

Anyone remember their HIGH SCHOOL science classes? How about this equation?

F = M * A or Force equals Mass times Acceleration

Force is the total power that your car has, its engine's output

Mass is how much the whole things weighs (car, fuel, junk, you, etc.) all together.

Acceleration is how fast your increase your speed. In other words did you go 0-60MPH in 5 seconds or 20 seconds. If you did it in 5 seconds your Acceleration was greater.

Lets assume that you always accelerate at the same rate, it really doesn't matter how fast or slow, but its just the same.

If you apply this to the equation, ANY increase in Mass (weight of you, your junk, etc.) will ALWAYS require MORE Force.

How do you increase Force, you have to use MORE gas, period.

Every ounce counts, maybe not that one day or week, but over time it adds up. If you're in city stop and go traffic, then it adds up even quicker because you accelerate more often.

This is also why highway mileage is better, you accelerate less.

Wind resistance and your car's drag co-efficient are a whole other conversation. Do they make a difference, yes, under the right circumstances, but for the average driver, no.

Speaking of wind resistance, putting your tailgate down on your pickup actually DECREASES your mileage.

This suggestion is very minimal since high powered engines can carry the weight successfully. I don't carry extra heavy items though.

ayscrf - Gas only weights about 7# a gallon. You would need over 14 gallons before you get to 100#....& it wouldn't make that much difference till then. I find with my truck the weight doesn't matter at all but the "wind" really does. If I'm driving into the wind it will knock me way down on millage.
